Overview
IEC 60061-3:1969/AMD41:2010, titled Amendment 41 to Lamp Caps and Holders together with Gauges for the Control of Interchangeability and Safety – Part 3: Gauges, is a critical international standard issued by the International Electrotechnical Commission (IEC). This amendment updates the existing guidelines for gauges used to verify lamp caps and holders. The standard ensures the interchangeability and safety of lamp components by providing detailed specifications for gauges that test lamp cap and holder dimensions, fitting, and mechanical properties.
This standard is integral for manufacturers, testing laboratories, and regulatory bodies involved in the production, quality control, and certification of electrical lamps and their components. The document is part of the IEC 60061 series and subscribers can access the full, updated content via the IEC 60061 database.
